The relatives of the participants spoil the show. They should sit with public and not participate in the show or discussions. During the break they can very well encourage the contestant. No harm in that.
Also the contestants should NOT talk about Maa, Pitaji etc. They should highlight about their singing talent or specifics for that particular song or improvisations they have made in the original.
Mentors are advised to follow the same and refrain from talking love life and all the bull shit. They can highlight the singing talent only
